In chapter 3 section 4.1, "crwctl" assumes that the namespace CRW is deployed to is "workspaces". However when installing CRW, the instructions suggest to use a different namespace. Mismatched namespaces leads to the error:

»   Error: E_BAD_NS - Namespace does not exist.
»   The Kubernetes Namespace "workspaces" doesn't exist. The configuration cannot be injected.
